What idea did Charlemagne promote through his reign?

Charlemagne, also known as Charles the Great, played a significant role in the preservation and promotion of classical learning during his reign in the early Middle Ages. He established the Carolingian Renaissance, which was a revival of art, culture, and learning based on classical models. This movement sought to recover and preserve texts from ancient Greece and Rome. Charlemagne encouraged the establishment of schools, such as the palace school led by Alcuin of York, where scholars were brought together to study and teach. By promoting education, fostering the copying of manuscripts, and encouraging literacy among the clergy, Charlemagne ensured that classical knowledge was preserved and disseminated throughout his empire. This commitment to learning laid the groundwork for the later cultural developments in Europe, distinguishing his reign as a period of intellectual awakening in an otherwise tumultuous time.
